20100284563 | WATERMARKING DIFFERENT AREAS OF DIGITAL IMAGES WITH DIFFERENT INTENSITIES - An image is processed to encode a digital watermark, with different regions thereof processed using different levels of watermark intensity. In an image comprised of elements of differing sizes (e.g., halftone shapes of different sizes, or lines of different width), the different regions can be defined by reference to the sizes of elements contained therein. Regions characterized by relatively small elements can be watermarked at a relatively low intensity. Regions characterized by relatively large elements can be watermarked at a relatively high intensity. A variety of other features are also discussed. | 11-11-2010 |
20110214044 | Methods and Arrangements Relating to Signal Rich Art - Art is infused with network identifiers at the time of its creation, rather than as a post-process. The identifiers may be encoded as overt elements of the art, and enable the artist to reprogram—over time—an augmentation of the artwork experience via network-delivered components. These network components can include stimuli present when the artist created the work (e.g., music), commentary by the artist, video and augmented reality features, audience-crowdsourced content (e.g., imagery of, or feedback provided by, other viewers encountering the artwork), etc. The artwork augmentation can vary with the user's context (e.g., location, demographics, interests, history). Physical brushes can be equipped to insert such identifiers in graphic arts; other authoring tools are disclosed as well. The network experience can be delivered via smartphones, projectors, and other devices. A great number of other features and arrangements are also detailed. | 09-01-2011 |

20130311329 | IMAGE-RELATED METHODS AND ARRANGEMENTS - In one aspect, a user captures an image of a physical object (e.g., of a grocery item, using a smartphone). The depicted object is identified, such as by extracting fingerprint or watermark data from the imagery. Other imagery depicting that object—or depicting related objects—is identified on the web, and is displayed to the user on the smartphone screen. The user may select one or more of these images and direct that they be posted to a social network account (e.g., Pinterest) associated with the user. In another aspect, the user's location is sensed (e.g., an aisle of a department store), and a collection of images depicting nearby products is presented to the user for selection and posting to a social networking service. A great variety of other features and arrangements are also detailed. | 11-21-2013 |

20130057859 | METHOD AND DEVICE FOR DETERMINING THE QUALITY OF MEASUREMENT RESULTS OF A SCATTERED LIGHT METER - A method for determining the quality of the measuring results of a scattered light meter for measuring the particle concentration in motor vehicle exhaust gases, which has at least one scattered light measuring chamber, at least one light source and at least one light sensor, includes the steps: determining the difference between two scattered light sensor signals, that were picked up in a reference state of the scattered light meter; determining the difference between two scattered light sensor signals, which were picked up in a used state of the scattered light meter; and comparing the difference of the signals picked up in the used state to the reference signal difference of the signals picked up in the reference state. | 03-07-2013 |
20130057860 | DEVICE AND METHOD FOR CALIBRATING A SCATTERED LIGHT METER - A calibration apparatus for calibrating a scattered-light measuring device that is embodied to measure a particle concentration in motor vehicle exhaust gases, comprises at least one scattering body that has a number of scattering centers having a defined size and a defined mutual spacing. The scattering centers are disposed in such a way that the scattering body, upon irradiation with light from a light source, delivers scattered light having an intensity and a distribution predetermined by the scattering body. | 03-07-2013 |
20130182252 | SCATTERED LIGHT MEASURING METHOD - A scattered light method for measuring particle-dependent parameters of gases, in particular particle-dependent parameters of internal combustion engine exhaust gases or other colloids, includes introducing a particle-containing gas into a measuring chamber; emitting a light beam into the measuring chamber; receiving light scattered by the particles using at least two scattered light sensors, the scattered light sensors generating scattered light sensor signals, each being a function of the light received by the respective scattered light sensor; determining an average particle size from the scattered light sensor signals from at least two scattered light sensors and determining at least one further particle parameter from the previously determined average particle size and the scattered light sensor signals. | 07-18-2013 |
20130335739 | measuring device for measuring particulate matter concentrations using scattered light and method for monitoring the measuring device - A measuring unit for measuring a particulate concentration in exhaust gases using scattered light includes a measuring chamber, at least one light source and at least one light sensor, the measuring chamber being situated in the optical path of the light source; and the light sensor records the light scattered by the particulates in the measuring chamber. To detect the intensity of light beam that is relevant for a precise particulate measurement, a monitoring device is provided to detect the intensity of the light beam with the aid of a scattered radiation. The intensity of the light beam is recorded using a monitoring measurement, by ascertaining a scattered radiation and comparing it to a specified reference value for the scattered radiation. With the aid of the comparison, the intensity of the light source is regulated correspondingly and/or the measuring result of the particulate measurement is correspondingly corrected. | 12-19-2013 |
20140230523 | DEVICE AND METHOD FOR MEASURING THE PARTICLE CONCENTRATION IN AN AEROSOL - A device for measuring the particle concentration in an aerosol using a flow tube includes a cavity in which there is a sleeve, the cavity branching off from the flow tube. The sleeve includes, at its end facing away from the flow tube, a collar. The collar encircles the periphery of the sleeve and is fastened at the periphery of the cavity. There is one or more inflow openings in the collar. At least one outflow opening is in an end of the sleeve, which end extends into the flow tube. A measuring chamber is also included in the cavity on the side of the sleeve facing away from the flow tube. | 08-21-2014 |
